A Cohoes man was charged with weapons possession after he was apprehended following a foot chase, Troy police said Wednesday.

Police credit two bystanders who they say confronted the armed man, as well as a coordinated response by officers.

Donald Lewis III has also been charged with obstructing governmental administration, said police.

Police were called about 2:45 p.m. Wednesday to the area in the first block of Fourth Street for a fight between two men. When officers arrived, one man fled.

As Officer Danielle Ashe gave chase, she let dispatchers know her location, which was broadcast, including a suspicion that the man might be armed. Soon, other cops joined the chase. Two bystanders near The Bethany Center on State Street blocked the suspect and got physical with him, which prompted him to draw a gun on them, police said. The officers screamed at him to drop the gun. He did and was taken into custody.
